Abstract
Abstrak - Struktur bangunan lepas pantai dibangun disebuah fabrikasi di darat dan
kemudian dipindahkan ke laut di mana bangunan tersebut akan beroperasi.
Transportasi bangunan lepas pantai membutuhkan pengikatan yang kuat supaya
dalam proses transportasi, struktur tetap aman dan terjamin. Tugas akhir ini
membahas tentang keandalan struktur seafastening pada transportasi jacket
platform ke South East Sumatera Block. Struktur yang dianalisis adalah jacket
platform Banuwati dengan menggunakan barge EOS-281. Pemodelan jacket dan
barge menggunakan bantuan perangkat lunak komputer. Untuk melihat gerakan
barge selama transportasi dilakukan analisa stabilitas dan juga RAO keadaan
lightship, half load, dan full load. Hasil perhitungan RAO untuk gerakan heave,
roll dan pitch berturut – turut adalah sebesar 0,99 m/s, 4,92 deg/m dan 0,989 deg/s.
Tegangan aksial maksimum terdapat pada member 0003 – 0100 sebesar 14,02 ksi
dan member 0005 – 0083 sebesar 13,93 ksi. Keandalan struktur seafastening
dengan memperhatikan 2 member dengan tegangan aksial terbesar masing-masing
99,63% dan 99,85%
============================================================================================Abstrak - The structure of offshore building is constructed in a fabrication on land
and then transferred to the ocean where the building is going to operate. Offshore
building transportation requires a strong binding, so that in the transport process,
the structure remains safe and secure. This paper discuss about reliability analysis
of seafastening structure in transportation Banuwati Jacket Platform to South East
Sumatera Block. The structure that analyzed is the banuwati platform jacket with
using barge EOS-281. Modelling jacket and barge are using computer software. To
see the movement of the barge during transportation performed stability analysis
and also RAO lightship, half load and full load. The results of calculations for the
movement RAO heave, roll and pitch are respectively of 0.99 m / s, 4.92 deg / m
and 0.989 deg / s. The maximum axial stress contained in the member 0003 – 0100
amounted to 14,02 ksi and member 0005 – 0083 amounted to 13.93 ksi. Reliability
structure seafastening by observing two maximum axial stress members
respectively 99,63% and 99.85%
